ARCHIBALD IVIETING, OF MIDDLETOIVN, PENNSYLVANIA.

COOKING-STOVE.

Specication of Letters Patent No. 3,860, dated December 16,-` 1844.

To all whom t may concern.'

Be it known that I, ARCHIBALD VIETING, of Middletown, in the county ofDauphin and State of Pennsylvania, have invented a new and useful`Improvement in Cooking- Stoves, which isdescribed as follows, referencebeing had tothe annexed drawings of the same, making part o-f thisspecification.

Figure l is a perspective view of the stove with the side and backplates removed, showing a part of the interior arrangement. Fig. 2 is ahorizontal section through the lower flues. Fig. 3 is a horizo-ntalsection through the upper flues. Fig. 4 is a horizontal section throughthe middle iiues. Fig. 5 is a vertical longitudinal section on the line.r of Figs. 2 and 3. Fig. 6 is a l vertical section through the pipe,and force or section pump c. Fig. 7 is a perspective view of the wholestove.

The general arrangement of the irechamber A-small oven B-boiler holes C-large oven D-funnel E, and hearth F-is similar to other cooking stovesin use.

The improvement that I have made is in the arrangement of the flues forthe proper diffusion of the heat throughout the stove for regularity andeconomy in cooking and in the arrangement of certain dampers forchanging the direction of the heat at pleasure--and likewise in thearrangement of'a force or suction pump in combination with the stove forproducing a draft through the stove before it is heated.

Between the lire chamber A, and the small oven B, I form a verticalspace eX- tending from one side of the stove to the other; in the middleof which I place a vertical plate p extending across said space, fromthe top plate `of the large oven, to the level of the top plate of thesmall oven,

, thus dividing said space into twovertical diving iues G, I-I, whichlead into horizontal side fines I, J, extending to the front of thestove and dividing the space between the ovens and hearth into threefines by vertical `turning plates K, K, arranged' directly under t-helower edge of the plate forming the back of the first mentioned flues G,IVI. When the plates 7c, 7a, are turned and brought to a horizontalposition, the flues I, J, will communicate the one with the other,between the two ovens. The fines' I, J, where they pass under the hearthare formed into the aforesaid two side flues by the side plates of theash pit L, which plates also form` the inner sides of said fines. Theseflues I, J, lead into a space formed between the front of the largeoven, and the front of the stove, said space being divided by a verticalcross plate a, into two front .diving. flues M, `N. These tiues leadinto twozig-zag flues P, Q, eX- tending the whole length and breadth ofthe stove, and of the` large oven, under which they pass, one of `saidfront diving flues leading into one of said zig-zag fines, and

the other diving' flue into `the opposite zigzag flue. These tlues P, Q,lead into two rear ascending flues R, S, that lead into the smoke funnelE, at the rear of the small oven B. The vertical cross plate T thatdivides the space behind the large oven into the two rear ascending'iiues extends from the bottom plate of the stove to the level of thebottom of the small oven. Upon the top or in this plate, turns one ofthe pivots of a turning damper U, for changing the draft. The otherpivot forms also the handle, and passes through the side of the stove.There is another turning damper V placed at the junction of the flue I,with the Iiue R, for uniting 0r Vseparating said lues at pleasure` Oneof its pivots passes through the opposite side of the stove and forms ahandle by which it is turned. lVhen these dampers U, V, are in theposition represented in Fig. l, the draft will be in the direction ofthe arrows, obliquely across from one of the rear corners, to theopposite front corner. Through the fines I, J, to the front diving i'lueN, through which it will descend to the flue Q and after passing throughsaid flue will ascend through the iue R to the funnel, having previouslypassed down flue II along flue J, down iiue M, and back through thezigzag' flue P and vertical iue S, by which the smoke and heat are made tocirculate twice, entirely through the stove. There is a direct flue obetween the perforated top plate of the stove and the top of the smalloven leading from the lire chamber to the funnel. This iiue is dividedfrom the fire chamber by a vertical plate Y and the sliding dampers W'and X. It is also separated at the middle into two sections by a centralplate q l When the stove is cold, there will be very little draft andtherefore in order to produce a partial vacuum in the stove at the rearpart thereof I have combined and arranged a suction or force pump cWhich is placed at an opening leading into the funnel, or in anyconvenient place, and when operated in the manner of a pump, willproduce a draft from. the lire-chamber to the funnel.

A sliding damper W, before referred to is made to slide back and forth,over one third of the space, forming` the flue leading from the rechamber to the funnel, over the small oven, for opening and closing saidflue at pleasure, and for directing the heat to the side boilers. Theopposite damper X, is fora similar purpose. There is also a horizontalsliding damper Z, placed over the entrance to the flue Gr to be closedWhen it is required to turn the draft directly from the fire chamberdown the flue H, as described and represented. When this damper and thedamper U are open the draft Will pass through all the fluessimultaneously.
